' To all whom it may concern:

\ Be it known'that I, EDWIN E. SLICK, of

Pittsburg, Allegheny county, Pennsylvanla, have invented a new anduseful Hotbed for Rolling Mills, of which the following is a full,

" clear, and exact description, reference being,

had to the accompanying drawings, forming part of this specification, mwhich Figure 1 is a top planview showing a portion of my improvedhotbed, the bed proper being broken away in the lower half of the view.Fig. 2 is an irregular vertical crosssection on a larger scale. Fig. 3is a central longitudinal section showing a central portion of thetable, and Figs. 4 and 5 are respectively a partial plan view and avertical cross-section showing a part of the central portion of amodified form of the invention.

My invention relates to the hotbeds employed for receiving the rolledsections from a rollin mill and is designed to increase the capacity ofthe bed for handling therolled metal and increase the rapidity of theoperations. The invention consists in providing a guidin -runway inwhich the metal is recelved,

thisrunway havin side guidesin connection with means for eit er ralslngthe metal from the runway and moving it sidewise or movin the metasidewise.

ing the side uides vertically and then movt further consists inpushermechanism for acting upon the metal to move it sidewise, which pushermechanism contacts with the rolled piece throughout its length, orsubstantially so. This is of special advantage in connection with metalof small cross-section such as small angles, channels,- &c..-in whichthe metal is liable to be bent by the pushers heretofore used.

The invention alsoconsists in using a receiving-runway which isstationary so far as lateral motion is concerned in connection with aside pusher, which moves the metal from the runway sidewise'upon thehotbed, and, further, in t e above combination, where hotbeds areprovided on each side of the runway, the pusher being adapted to movethe metal to elther side. r

It further consists in the construction and arran ement of parts, ashereinafter more fully described, and set forth in the claims.

In the drawings, referring to the form of A "Fi s. 1, 2, and 3, 2 reresentsa longitudinal guiding-runway, whic is in front of the fin-.ishinging si e uide the metal as it is fed forward. In this orm therunway is stationary and issupported upon a longitudinal box-girder 3.mounted upon a foundation 4. The runway'is of hollow box form, as shownin Fig.

2, and is provided with transverse recesses'ordepressions- 5, throughwhich the shoes for the pushers move -transversely. The runway 2 isdisposed cent-rally of the hotbed,

which is shown as consisting of oppositelyinclined separated bars 6 6,extending from' the runway to lines of feed-rollers 7 7, lo- 'catedat'the opposite sides of the bed. The pusher for moving the metalsidewise upon the hotbed consists of a continuous section, which isshown as formed of achannel 8,

ass of a rolling-mill, this runway havguiding portions which hold andbolted to the separated shoes 9. These shoes are spaced at suitableintervals apart between the'bars 6 and are provided with outwardly anddownwardly inclined surfaces 10 10, extendin from the channel-section. 2

ends of chains 17, secured, through turnbuckle connections 18, to across-head 19. The cross-head 19 is, centrally secured to the inner endsof the plungers 20, moving in hydraulic cylinders 21. The cylinders 21are preferably single acting and are controlled by suitable 'valvemechanism, throu h which the shafts 15 may be rotated in eit erdirection. Some'of the shoes 9' are not so conwhich extend over centralg nected to the wire ropes, but are merely bolt.- j ed to and carried bythe pusher. The rollers I p 7 are mounted in suitable bearings uponlongitudinal beams22, carried upon supports 23 over the shafts 15 andbeneath the ends of the bars 6. The shoes 10 are preferably transverselybeveled or inclined on their wings toward the entering side of themetal,

so that if the pusher happens to be in a position near the center of t etable, where the incoming metal would contact with the wings, the end ofthe entering metal will-not strike-the square side of the wing and causeIIO injury to i the apparatus: These inclined faces are, shown at 24 inFig. 3. 1

In the operation ofthe apparatus the metal is fed forward from therolling-mill 5 into and alon the runway, by which it is guided and he (1in place. The valve mechanism of the cylinders 21 is then actuated tomove the pusher 8 sidewise of the bed. As this pusher approaches therunway the inclined wings will lift the rolled piece, and the outer sideface of the channel 8 will then push it sidewise out of the runway. If aseries of sections are retained on either side of the rum way, thepusher will actuate the grou and [5 move the outer one upon the setof rolers 7 atsuch side. It will be noted that the metal is properly receivedin the stationary runway irrespective of the position of the pusher, andthe pusher may then be actuated to move the metal to the opposite sideof the bed from that at which the pusher'is resting when the ieceenters;

In the orm of Figs. Land 5 the runway consists of a channel 25, with theflanges proj ecting downwardly, and the side guides con- 'sistofseparated tilting sections 26-, arranged,

in pairs. Each of these .sections'is of. lever form,"carried by a shaftor rod 27 and having a counterweight 28. Each section also has a 0lateral wing 29 with an inclined upper edge. In this form the pusherconsists of a;plain channel-section 30, without wings or inclined shoes,and as it approachesthe guides.

in its lateral movement it rides up over the inclined wings anddepresses both sets of guides which are connected by the rods or shafts27 The side guides "will thus be forced down through slots at thesides-of the .centr'al channel, and the pusher will then forcethe-rolled sectionsidewise over the 'depressed guides and upon thehotbed proper.

Afterth'e' pushe'r'has passed the wings ofthe guides the 'counterweights"will swing the ckto their raised position, so that guides be properlyguided and the nex piece will held-in the runway.

the use of a stationary runway which is always in position to receivethe metal and-is provided with side guides to hold it in place andprevent its curving outwardly to either side, and. further from the useof-a pusher which 'is move bodily and sidewise of the bed and whichremoves the metal'from;the runway and carries itonto the bed. Theyfurther result from the substantial continuity of the pusher; whichprevents bending of pieces of small cross-sect1on, during the pushingoperation. c I

The metal may be received uponthe-hot: bed no matter what the positionof the pusher. The capacity ofthe table isytherefore increased, and themetal may be handled rapidly. The form and arrangement of the table,

. The advantages of-my'invention result fromthe runway, the ushermechanism, 850., may be varied wide ywithout departing from myinvention.
